When you install Horizon Agent on a virtual machine, you can select or deselect custom setup options. In addition, Horizon Agent installs certain features automatically on all guest operating systems on which they are supported. These features are not optional.

To learn which features are supported on which guest operating systems, see "Feature Support Matrix for Horizon Agent" in the Horizon 7 Architecture Planning document.

To change custom setup options after you install the latest Horizon Agent version, you must uninstall and reinstall Horizon Agent. For patches and upgrades, you can run the new Horizon Agent installer and select a new set of options without uninstalling the previous version.

All custom setup options are selected by default except USB Redirection, Scanner Redirection, Smartcard Redirection, Serial Port Redirection, Flash Redirection, Skype for Business, VMware Horizon Instant Clone Agent, HTML5 Multimedia Redirection, Horizon Performance Tracker, VMware Virtual Print, and SDO Sensor Redirection.
